I/O modules

Product Overview

The GE IC693CHS398H expansion base provides five additional I/O slots for the Series 90-30 control system. This unit connects directly to a CPU or another expansion base through a dedicated cable. It effectively increases the total I/O capacity without requiring a complete system redesign. The base incorporates a built-in power supply for powering installed modules.

Technical Specifications

Expansion Architecture

This expansion base connects to the host CPU via a 50-pin shielded ribbon cable. The GE IC693CHS398H extends the backplane bus to support five additional modules. Each slot accommodates any Series 90-30 I/O module, including high-speed counter and motion control types. The base automatically configures its address space after system power-up.

Power Distribution System

The integrated power supply delivers 5 VDC at 30 amperes and 24 VDC at 1.5 amperes across the backplane. This capacity supports a wide variety of mixed I/O configurations within the five slots. The supply includes overcurrent and overvoltage protection for safeguarding connected modules. It uses auto-ranging input circuitry that accepts 120 or 240 VAC without manual adjustment.

Mechanical Design and Mounting

This unit measures 20.3 centimeters in width and weighs approximately 1.36 kilograms. Its steel chassis provides robust protection against physical damage and electromagnetic interference. You can mount the GE IC693CHS398H vertically on a panel or horizontally on a DIN rail. The enclosure includes ventilation slots for passive cooling during continuous operation.

Connectivity and Cabling

The expansion interface uses a 50-pin connector with positive-locking latches for secure attachment. You should use the recommended shielded cable to maintain signal integrity over longer distances. The base also provides a grounding terminal for connecting the chassis to the system ground. This design minimizes noise coupling and ensures reliable communication with the main CPU.

Environmental Operating Range

This expansion base operates within a 0°C to 60°C ambient temperature range. It tolerates humidity levels from 5% to 95% without condensation. The unit meets UL 508, CSA 22.2, and CE marking requirements for industrial use. Therefore, it performs dependably in manufacturing, process control, and utility applications.

Application Scenarios

System integrators use this base to add I/O points for expanding machine functionality. It works well in retrofit projects where existing chassis lack available slots. The GE IC693CHS398H also supports distributed configurations where you place I/O near field devices. This approach reduces wiring costs and improves system response times significantly.
